7 1 Claim. (Cl. 124-16) 7 The present invention relates to guns and particularly relates to toy guns adapted to shoot darts.

One of the primary objects of the present invention is to provide an improved gun of the type mentioned which is shaped to simulate a rifle having pump means for cocking the same.

Another object of the invention is to provide an improved gun of the type mentioned having an improved pump action means whereby the projecting spring is compressed to cock the gun and is then latched in cocked position while the pump grip or handle is then returned toits initial position.

Another object of the invention is to provide an improved means whereby the dart is held in the gun and cannot accidentally drop therefrom until the trigger releases the projecting spring.

Another object of the invention relates to improvements in the construction and'arrangement of the elements whereby the gun construction may be economically manufactured.

Other objects of the invention will become apparent from the following specification, the drawings relating thereto and from the claim hereinafter set forth.

Fig. 11 is a fragmentary cross-sectional view taken substantially along the line :il-H of Fig. 2.

Referring-to the drawings, the toy gun'which is I illustrated is shaped to simulate a rifle having a stock [0 connected to the frame portion E2 of a sheet metal casing which is shaped to provide a barrel l4.

The barrel I4 is shaped to provide an upper longitudinally extending chamber l6 and a lower longitudinally extending chamber .18 which intercommunicate through the reduced neck vportion 20 therebetween. The chambers l6 and it are generally circular in shape, and the lower chamber l8 is provided witha longitudinally extending slot 2-2 on the underside thereof.

A longitudinally extending tubular member 24, which is generally circular incross section and which has a longitudinally extending slot 25 formed in the top thereof, is mounted within the chamber l8 within the forwardend thereof. The member 24- is mounted in spaced relation with thewalls of chamber IS with the axis of both substantially coinciding, and the forward end thereof is mounted on a washer -28 havinga centralopening 3'0 therethrough. The Washer'28 is provided with outwardly extending tabs 32 which extend through corresponding slots or apertures formed in the barrel l4 adjacent the forward end thereof. Inwardly struck tabs '34 are formed on the forward edge of the barrel at spaced intervals therearound and bear against the front face of the washer 28 so that it is fixed with respect to the casing.

The rear end of tubularmember 2 4 is provided with out-struck tabs 36 at diametrically opposed points which serve to space the rear end of the member 24 from the side walls of the chamber 18 and abut against in-struck tabs 38 formed in the wall of'chamber [4 so that the tubular member 24- is fixed with respect to the casing.

A spiral spring 40 is mounted in embracing relationship to the tubular member 24 with the innermost convolution of the spring abutting against the tabs 36 so as to limit movement of the spring and so that the spring is compressible and expansible longitudinally of the barrel. The forwardmostconvolution of the spring is adapted to bear against a washer 4-2 which slidab-ly embraces the tubular member 24 and which has a radially inwardly extending tab formed there- -on which is adapted to project through the iongitudinally extending slot 26.

The spring 40 is adapted to be compressed to its cocked position by means of pump means which are slidable longitudinally of the barrel.

member 46 adjacent the rear end thereof. The Y member 50 is provided with a U-shapedrecess 52, which receives the member 46 therein, and

such member 46 is provided with a depending struck-out portion 54 which extends through an aperture in the member 50 and terminates in outstruck tabs 56 so that the handle 50, is securely attached to the member 46.

ward the stock, the member 46 will slide on the flanges 48 with respect to the barrel I4.

The forward end of the member 46 is provided with upstanding projections at each side thereof. The projection on one side is indicated at 58 and is curved about the tubular member 24 on a curvature about the center of the barrel. The opposite edge is provided with a projection 60, which is complementary in shape to the projection 58. wardly extending straight portion 62 which extends through the reduced neck 20 into and across chamber I6.

It will thus be seen that the portions 58 and 66, which project within chamber I8, arelocated forwardly of the washer 42 and abut thereagainst. When the handle 50 is pulled rearwardly the member 46 is also pulled rearwardly, so that the spring 40 is compressed from the position shown in Fig. 2 to that shown in Fig. 3.

Another spiral spring 64 is disposed within the upper chamber I6, adjacent the forward end thereof. The rear end of the spring 64, abuts against an in-struck tab 66, formed in the casing I4, and the forward end of the spring embraces a projection 68 formed along the rear edge of projection 62. Thus, as the member 46 is pulled rearwardly from the position shown in Fig. 2 to that of Fig. 3, the spring 64 is likewise compressed. 7 A

Means are provided for releasably engaging the washer 42 to hold the spring 40 in its compressed or loaded position, until released by the trigger. Such means include an elongated trigger lever I0, which is pivotally mounted to the casing by the pivot pin I2. The member I is provided with a longitudinally extending rib to stiffen the same, and the rear end projects within the frame portion I2 to a position above trigger I4. The trigger I4 is pivotally mounted to the casing by pivot pin I6 and has the usual depending finger engaging portion and also has upwardly extending fingers I8 which are alternatively disposed on opposite sides of member 10 so that such member is movably received therebetween. The rear edge of trigger 14 is provided with an upstanding projection 80 which is adapted to bear against flanges 82 formed on the under edge of member 10 at the rear thereof. As the trigger is pulled rearwardly, the projection 80 strikes against the rear end of lever I0 to move such rear end upwardly. V

The rear end of mem er i0 is resiliently urged downwardly and the forward end of member I0 is urged upwardly by a spring member 84, which It will thus be seen that by grasping the handle and pulling it to-- of the lever I0 is provided with an upstanding pro ection 90, providing a shoulder 92 and having a rounded front corner 94. The top edge of the projection 90 is of a length greater than the distance between the adjacent convolutions ofthe spring 40 when such spring is extended, so that suchfspring will freely slide over the projection 90.

When the spring 40 is compressed to the position shown in Fig. 3, it will be seen that the pro- The projection 60 terminates in an upbears against the inside of the casing, is passed jection 90 is snapped upwardly in front of washer 42 so thatv such washer is releasably engaged by the shoulder 92. The projection 90 extends inwardly beyond the peripheral edge of the washer 42 and extends through a slot 96 formed in tubular member 24. As soon as the washer 42 is engaged by the projection 90, the grip 50 may be released and the pump means, including the grip 50 and member 46, will be returned to their initial position shown in Fig. 2 through the action of the spring 64, and the parts will assume the positions shown in Fig. 4. a

As stated above, the gun is adapted to shoot darts, and such darts may be of any desired form, but in the embodiment illustrated comprise a stem I00 of uniform diameter throughout the length thereof with a suction cup I02 secured to the forward end thereof. The dart is adapted to be positioned within the tube 24 as shown in Fig. 4, so that an inner end of the stem I00 abuts against the radial tab 44 of washer 42. Asthe shaft I00 is pushed inwardly to such position it will be seen that the projection 90, which projects into the tube 24 through the aperture 96, will be resiliently urged outwardly to a slight extent due to the fact that the inner end of the dart bears against the top edge of the projection 90. Such projection will thus be resiliently urged against the dart while the dart is in this position, through the action of the spring 84, so that the dart will be held in the gun and cannot accidentally drop therefrom.

When the trigger I4 is pulled, the projection will raise the rear end of lever I0 so that the projection will be withdrawn from engagement with the dart and the washer 42 so that the spring 40 will be released. The dart will then be projected from the gun by the thrust of the tab 44 against the inner end of the dart.

Formal changes may be made in the specific embodiment of the invention described, without departing from the spirit'and scope ofthe invention, the scope of which is commensurate with the appended claim.

What is claimed is:

In a toy spring gun shapedto simulate a rifle and adapted to shoot darts, a sheet metal casing having a barrel portion, said barrel portion having upper and lower intercommunicating ,longitudinally extending chambers each of which is substantially circular in cross-section, the-lower chamber being provided with a longitudinally extending slot in theunderside thereof, a spiral spring mounted within said lower chamber adjacent the'forward end thereof and compressible and expansible longitudinally thereof, another springs are compressed when said member is slid rearwardly of said barrel, means releasably engaging said first named spring when said first named spring is compressed, the construction and arrangement being such that said another spring returns said member to its initial position after said first named spring is releasably engaged.
